Planet Earth, an arena of 'sovereign' countries in their historical struggle for power, has been in the state of permanent anarchy. The League of Nations and the United Nations with voluntary membership have not changed this condition.

To preserve it, control nuclear arms, eliminate neuralgic points and preclude armed conflicts on the globe, a world-wide public authority, resting on the compulsory membership of nations, is imperative.
